OpenBSC with A-interface
by Dmitri Soloviev 07 Sep '13

Hi list, Peter, thank you for your reply. I still have questions about media control: 1) when parsing MGCP CRCX, sdp is not expected. May I change it? 2) I still can't run media in BSC mode. Seems I'm missing something. osmo-bsc and osmo-bsc_mgcp are running BSSAP works perfectly But it seems two interfaces are working completely independent: -- MGCP between MSC and BSC -- interface between BSC and BTS (ip.access): at MGCP, connection is acknowledged, endpoint is allocated (at BSC ip=192.168.1.11) at ip.access interface between BSC and BTS, BTS replies to ip.accessCRCX with proper acknowledgement with proper ip:port at BTS (192.168.1.9) , then BSC issues ip.accessMDCX with endpoint ip zero: 7e:73:01:09:f8:00:2d:*f0:00:00:00:00*:f1:0f:be:f4:00:f2:03 My attempts to modify connection at MGCP interface has no impact on ip.access interface The key question, I'm not getting how osmo-bsc and osmo0bsc_mgcp are interacting.

l1-sap patches for osmo-bts
by Andreas Eversberg 04 Sep '13

04 Sep '13

hi, i reworked my l1sap patches for osmo-bts. (they are the base for adding osmo-bts-trx model code, which allow support for OpenBTS transceivers, like UmTRX or Calypso-BTS.) each single patch was tested, if Sysmocom-BTS is still functioning after applying it, rather than testing all patches together. i do not send the patches to mailing list, since there are 21 patches, and i don't want to spam the list before i know that these patches are small enough to be reviewed and understood. the branch is jolly/l1sap_parts. please let me know, whether they require better description or finer splitting. regards, andreas from last path to first patch: commit 0c0229886f6f6eba029c044e4cac8b420d86cd1c Author: Andreas Eversberg <jolly(a)eversberg.eu> Date: Sun Sep 1 12:30:52 2013 +0200 Remove obsolete gsmtap handling from osmo-bts-sysmo part. commit dfc8a3635e527960fa615c4ce7342e9739230a79 Author: Andreas Eversberg <jolly(a)eversberg.eu> Date: Sun Jun 16 15:09:56 2013 +0200 sysmobts: Forward CMR from L1 (Phone) to RTP payload commit 8cfffc712914107fe8277c96ad3afb1891f25014 Author: Andreas Eversberg <jolly(a)eversberg.eu> Date: Sun Sep 1 12:06:19 2013 +0200 Add gsmtap option to command line to main.c of osmo-bts-sysmo commit 8ca47efb9cf9861a2766c41b96469263e1e13ed9 Author: Andreas Eversberg <jolly(a)eversberg.eu> Date: Sun Sep 1 12:04:49 2013 +0200 Move gsmtap VTY commands from osmo-bts-sysmo to common part commit 2653aee1604d1504d707c9ed264dcb5cdaf2b01d Author: Andreas Eversberg <jolly(a)eversberg.eu> Date: Mon Jul 29 09:45:22 2013 +0200 Send primitives at PH-/MPH-/TCH-SAP interface via GSMTAP commit 66c08e87a2985ffd48e6d870ac6318c2b82a1476 Author: Andreas Eversberg <jolly(a)eversberg.eu> Date: Sun Sep 1 11:57:07 2013 +0200 Move loopback control VTY commands from osmo-bts-sysmo to common part commit 8015bfcb3014c707bfe16ed4b52612e6fe377e75 Author: Andreas Eversberg <jolly(a)eversberg.eu> Date: Thu Feb 14 11:17:58 2013 +0100 Correctly fill system information messages from BSC SI 5*/6 require L2 header of 0x03,0x03.

[PATCH 1/6] vty: Fix BSC_NODE prompt string
by Jacob Erlbeck 02 Sep '13

02 Sep '13

Change '%s(bsc)#' to '%s(config-bsc)# '. The missing trailing blank brakes osmopy's VTYInteract.command() because the blank is contained in the end patterns which are checked to decide whether to leave the select loop. Thus trying to execute the 'bsc' command there blocks the test script forever. --- openbsc/src/osmo-bsc/osmo_bsc_vty.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/openbsc/src/osmo-bsc/osmo_bsc_vty.c b/openbsc/src/osmo-bsc/osmo_bsc_vty.c index 8eaa55b..f6cf1a0 100644 --- a/openbsc/src/osmo-bsc/osmo_bsc_vty.c +++ b/openbsc/src/osmo-bsc/osmo_bsc_vty.c @@ -43,7 +43,7 @@ static struct osmo_msc_data *osmo_msc_data(struct vty *vty) static struct cmd_node bsc_node = { BSC_NODE, - "%s(bsc)#", + "%s(config-bsc)# ", 1, }; -- 1.7.9.5

SMPP Submit_SM sender address
by Alexander Chemeris 30 Aug '13

30 Aug '13

Hi Harald, We're trying out SMPP interconnection and found that for Submit_SM (aka MT-SMS) sender is always set to an extension of subscriber ID 1. Looking into the code, this happens because we set "sms->sender" to point to subscriber ID 1 in submit_to_sms() function in SMPP code: /* fill in the source address */ sms->sender = subscr_get_by_id(net, 1); sms->src.ton = submit->source_addr_ton; sms->src.npi = submit->source_addr_npi; strncpy(sms->src.addr, (char *)submit->source_addr, sizeof(sms->src.addr)-1); And then src.addr/ton/npi are ignored when we store to the SMS DB and only subscriber ID is stored: /* FIXME: correct validity period */ result = dbi_conn_queryf(conn, "INSERT INTO SMS " "(created, sender_id, receiver_id, valid_until, " "reply_path_req, status_rep_req, protocol_id, " "data_coding_scheme, ud_hdr_ind, dest_addr, " "user_data, text) VALUES " "(datetime('now'), %llu, %llu, %u, " "%u, %u, %u, %u, %u, %s, %s, %s)", sms->sender->id, sms->receiver ? sms->receiver->id : 0, validity_timestamp, sms->reply_path_req, sms->status_rep_req, sms->protocol_id, sms->data_coding_scheme, sms->ud_hdr_ind, q_daddr, q_udata, q_text); So when we read SMS back from the DB, sender address is taken from that subscriber. It seems that a solution is to store actual ton/npi/addr in the SMS DB instead of storing ID. Then we could set sms->sender to NULL and just ignore it. Is there anything wrong with this approach? Otherwise we'll work on a patch to implement that. PS What is the current policy about changing DB layouts - just increase SCHEMA_REVISION? -- Regards, Alexander Chemeris.

[PATCH] nanobts: Fix initialization of two concurrent BTS.
by Holger Hans Peter Freyther 29 Aug '13

29 Aug '13

From: Holger Hans Peter Freyther <holger(a)moiji-mobile.com> It was possible that the wrong NSEI information was sent to the BTS. This is because patch_nm_tables is not called before sending the data to the BTS. This will break when two BTS connect more or less at the same time. Stop using the arrays directly and instead introduce a method that will patch the table and return the data and length. This makes sure that all users patch the table before we send the data to the BTS. --- openbsc/src/libbsc/bts_ipaccess_nanobts.c | 66 ++++++++++++++++++++++++------- 1 file changed, 51 insertions(+), 15 deletions(-) diff --git a/openbsc/src/libbsc/bts_ipaccess_nanobts.c b/openbsc/src/libbsc/bts_ipaccess_nanobts.c index c8b235d..dfc8d16 100644 --- a/openbsc/src/libbsc/bts_ipaccess_nanobts.c +++ b/openbsc/src/libbsc/bts_ipaccess_nanobts.c @@ -265,6 +265,40 @@ static void patch_nm_tables(struct gsm_bts *bts) } } +static uint8_t *nanobts_attr_bts_get(struct gsm_bts *bts, size_t *data_len) +{ + patch_nm_tables(bts); + *data_len = sizeof(nanobts_attr_bts); + return nanobts_attr_bts; +} + +static uint8_t *nanobts_attr_nse_get(struct gsm_bts *bts, size_t *data_len) +{ + patch_nm_tables(bts); + *data_len = sizeof(nanobts_attr_nse); + return nanobts_attr_nse; +} + +static uint8_t *nanobts_attr_cell_get(struct gsm_bts *bts, size_t *data_len) +{ + patch_nm_tables(bts); + *data_len = sizeof(nanobts_attr_cell); + return nanobts_attr_cell; +} + +static uint8_t *nanobts_attr_nscv_get(struct gsm_bts *bts, size_t *data_len) +{ + patch_nm_tables(bts); + *data_len = sizeof(nanobts_attr_nsvc0); + return nanobts_attr_nsvc0; +} + +static uint8_t *nanobts_attr_radio_get(struct gsm_bts *bts, size_t *data_len) +{ + patch_nm_tables(bts); + *data_len = sizeof(nanobts_attr_radio); + return nanobts_attr_radio; +} /* Callback function to be called whenever we get a GSM 12.21 state change event */ static int nm_statechg_event(int evt, struct nm_statechg_signal_data *nsd) @@ -278,6 +312,9 @@ static int nm_statechg_event(int evt, struct nm_statechg_signal_data *nsd) struct gsm_bts_trx_ts *ts; struct gsm_bts_gprs_nsvc *nsvc; + uint8_t *data; + size_t data_len; + if (!is_ipaccess_bts(nsd->bts)) return 0; @@ -300,9 +337,8 @@ static int nm_statechg_event(int evt, struct nm_statechg_signal_data *nsd) case NM_OC_BTS: bts = obj; if (new_state->availability == NM_AVSTATE_DEPENDENCY) { - patch_nm_tables(bts); - abis_nm_set_bts_attr(bts, nanobts_attr_bts, - sizeof(nanobts_attr_bts)); + data = nanobts_attr_bts_get(bts, &data_len); + abis_nm_set_bts_attr(bts, data, data_len); abis_nm_chg_adm_state(bts, obj_class, bts->bts_nr, 0xff, 0xff, NM_STATE_UNLOCKED); @@ -315,7 +351,6 @@ static int nm_statechg_event(int evt, struct nm_statechg_signal_data *nsd) trx = ts->trx; if (new_state->operational == NM_OPSTATE_DISABLED && new_state->availability == NM_AVSTATE_DEPENDENCY) { - patch_nm_tables(trx->bts); enum abis_nm_chan_comb ccomb = abis_nm_chcomb4pchan(ts->pchan); abis_nm_set_channel_attr(ts, ccomb); @@ -338,9 +373,9 @@ static int nm_statechg_event(int evt, struct nm_statechg_signal_data *nsd) if (bts->gprs.mode == BTS_GPRS_NONE) break; if (new_state->availability == NM_AVSTATE_DEPENDENCY) { + data = nanobts_attr_nse_get(bts, &data_len); abis_nm_ipaccess_set_attr(bts, obj_class, bts->bts_nr, - 0xff, 0xff, nanobts_attr_nse, - sizeof(nanobts_attr_nse)); + 0xff, 0xff, data, data_len); abis_nm_opstart(bts, obj_class, bts->bts_nr, 0xff, 0xff); } @@ -350,9 +385,9 @@ static int nm_statechg_event(int evt, struct nm_statechg_signal_data *nsd) if (bts->gprs.mode == BTS_GPRS_NONE) break; if (new_state->availability == NM_AVSTATE_DEPENDENCY) { + data = nanobts_attr_cell_get(bts, &data_len); abis_nm_ipaccess_set_attr(bts, obj_class, bts->bts_nr, - 0, 0xff, nanobts_attr_cell, - sizeof(nanobts_attr_cell)); + 0, 0xff, data, data_len); abis_nm_opstart(bts, obj_class, bts->bts_nr, 0, 0xff); abis_nm_chg_adm_state(bts, obj_class, bts->bts_nr, @@ -371,10 +406,10 @@ static int nm_statechg_event(int evt, struct nm_statechg_signal_data *nsd) break; if ((new_state->availability == NM_AVSTATE_OFF_LINE) || (new_state->availability == NM_AVSTATE_DEPENDENCY)) { + data = nanobts_attr_nscv_get(bts, &data_len); abis_nm_ipaccess_set_attr(bts, obj_class, bts->bts_nr, nsvc->id, 0xff, - nanobts_attr_nsvc0, - sizeof(nanobts_attr_nsvc0)); + data, data_len); abis_nm_opstart(bts, obj_class, bts->bts_nr, nsvc->id, 0xff); abis_nm_chg_adm_state(bts, obj_class, bts->bts_nr, @@ -424,11 +459,12 @@ static int sw_activ_rep(struct msgb *mb) */ int rc_state = trx->mo.nm_state.administrative; /* Patch ARFCN into radio attribute */ - nanobts_attr_radio[5] &= 0xf0; - nanobts_attr_radio[5] |= trx->arfcn >> 8; - nanobts_attr_radio[6] = trx->arfcn & 0xff; - abis_nm_set_radio_attr(trx, nanobts_attr_radio, - sizeof(nanobts_attr_radio)); + size_t data_len; + uint8_t *data = nanobts_attr_radio_get(trx->bts, &data_len); + data[5] &= 0xf0; + data[5] |= trx->arfcn >> 8; + data[6] = trx->arfcn & 0xff; + abis_nm_set_radio_attr(trx, data, data_len); abis_nm_chg_adm_state(trx->bts, foh->obj_class, trx->bts->bts_nr, trx->nr, 0xff, rc_state); -- 1.8.3.2

Newbie question on BS-11 firmware for first boot
by J.P. van Wyk 28 Aug '13

28 Aug '13

Good day list We acquired a BS-11 microBTS a while ago and in the preliminary stages of setting up the equipment came upon the following: background - 1. we installed OpenBSC as per the OpenBSC wiki. 2. we manufactured a serial cable to interact with the BS-11. 3. using bs11_config as per the bs11_config wiki page we started the BS-11 and got the following: $ ./bs11_config -p /dev/ttyUSB0 bs11_config (C) 2009 by Harald Welte and Dieter Spaar This is FREE SOFTWARE with ABSOLUTELY NO WARRANTY LMT LOGON: ACK PHASE: 1 Warm Up Abis-link: Down PHASE: 1 Warm Up Abis-link: Down PHASE: 1 Warm Up Abis-link: Down . . PHASE: 1 Warm Up Abis-link: Down PHASE: 1 Software required Abis-link: Down No valid safety Load file "BTSBMC76.SWI" After this nothing further happens. From the wiki page I conclude that the file in question is the SMU safety load that is needed to create the minimal configuration to get the BS-11 to boot. There seem to be another firmware image needed for the BS-11 namely the HS011106.SWL Am I correct in my assumption that the BS-11 was not preloaded with this software? Where do I get these firmware images as the wiki page states that the project can't provide any of the firmware due to copyright constraints.

[PATCH 1/2] bsc/ussd: Optionally send USSD message on MSC disconnection
by Jacob Erlbeck 28 Aug '13

28 Aug '13

Send an USSD message on each MS connection if the connection to the MSC has been lost. Add a vty config command 'bsc-msc-loss-txt' in 'config-msc' to set the notification string and to enable the feature.
